Demonstrating proper handwashing technique is critical for food safety and public health. The correct answer emphasizes the importance of using warm water, as this helps to loosen dirt and grease, making the washing process more effective. Scrubbing for at least 20 seconds is essential because this duration is sufficient to ensure that all areas of the hands—including between the fingers, under the nails, and around the wrists—are thoroughly cleaned, which helps to remove harmful pathogens.

This specific guidance aligns with best practices recommended by health authorities, which stress that thorough handwashing is one of the most effective ways to prevent the spread of illness, especially in food service settings. The combination of warm water and an adequate scrubbing time maximizes the effectiveness of soap in breaking down contaminants and killing germs.
